Coral Calcium Suppluments And Shellfish Allergies

Silliest of Yaks

Just wanted to pass along a warning from the Mayo Clinic website:

"Do not take coral calcium if you're allergic to shellfish. Coral calcium, which is obtained from ocean coral reefs, can trigger allergic reactions, such as hives, breathing problems and swelling, in people with shellfish allergies. "

- Open Original Shared Link

Unlike products that actually CONTAIN shellfish ingredients, coral calcium is not technically shellfish, and is available in supplements without any sort of warning label. Seeing as how many of us take calcium (either because we cannot tolerate dairy or have other absorption/bone density/neuro issues, etc) and food allergies and sensitivities seem so common among celiacs, it seems like others in the group might benefit from this warning.

I feel like I'm pretty smart about reading labels and the like, but this one somehow snuck past me. I didn't have an immediate reaction, but after taking the supplement on and off for awhile, I noticed that occasionally my tongue would get a bit swollen and I was getting unexplained hives. Given the amount of weird stupid health issues I have going on and haven't made sense of, it took until a near-anaphylactic experience (tight throat accompanied by hives and a HUGE tongue that barely fit in my mouth) for the lightbulb to go off that I was definitely having an allergic reaction to something. I took two Benadryl right away, which luckily did the trick, but looking back, maybe I should have used my epi-pen. I thought about everything I had eaten, medications I'd taken, and then it hit me. My calcium supplement was derived from coral, and I’d taken one within about a half-hour of the reaction. Duh. Anyway, be smart with the calcium supplements!

Some are also derived from oyster shell, but these are legally required (FDA major allergen labeling) to make note of it. Still something to look out for, since we all know that food and supplement labeling is an imperfect system!

      I'm not saying this is what you have, but your description reminds me of Morgellons, which are not very well understood. Here is a review from a reputable source. If it seems similar to your experience, you could raise this question with your Dr. https://my.clevelandclinic.org/health/diseases/morgellons-disease

      Celiac flare years after diagnosis

      Hi Trent, no dairy. Other than good quality butter. I have been lactose free for years. No corn, sugar, even seasonings and spices. I don't eat out. I cook my own food.

      @nancydrewandtheceliacclue, are you consuming dairy? Not sure if dairy is part of the carnivore diet.

      Celiac flare years after diagnosis

      Hello Russ! Thank you so much for your reply. I have not had an antibody test done, ever, relating to gluten. Last year I had an allergy test done via blood draw (as my insurance wouldn't cover the skin test) but this was for pollen and grasses, not food. Even on the blood test I had extremely high levels of reactions to each allergen. Could this seasonal...

      Celiac flare years after diagnosis

      The sensitivity of people with coeliac disease varies greatly between individuals. The generally accepted as safe limit for most people is 10 milligrams per day. This equates to a piece of bread the size of a small pea. Some people report that they are more sensitive than this, but others can very occasionally eat a normal gluten containing meal without reacting...

      Hello Russ! Thank you so much for your reply.  I have not had an antibody test done, ever, relating to gluten. Last year I had an allergy test done via blood draw (as my insurance wouldn't cover the skin test) but this was for pollen and grasses, not food. Even on the blood test I had extremely high levels of reactions to each allergen. Could this seasonal allergy inflammation be contributing to my celiac inflammation? I am so careful, there is no way I could ingest gluten. For example, couple of months ago I tried a cough drop that says it was gluten free. I checked ingredients, it seemed fine. But just taking one of those caused me to have nausea, vomiting, and the same extreme abdominal pain. Have you ever heard of anyone else having symptoms like mine after being diagnosed celiac and strictly gluten free? The last episode I had like this was yesterday, after I ate a certified gluten-free coconut macaroon with a little chocolate on it. I have eaten coconut and chocolate before with no issue,  so I didn't see how I could all of a sudden have such a strong response.

      The sensitivity of people with coeliac disease varies greatly between individuals. The generally accepted as safe limit for most people is 10 milligrams per day. This equates to a piece of bread the size of a small pea. Some people report that they are more sensitive than this, but others can very occasionally eat a normal gluten containing meal without reacting. I don't think that touching or throwing bread around would lead to you ingesting enough to cause a reaction. There are case reports of farmers with coeliac disease reacting to the dust from gluten-containing animal feed but they were inhaling large amounts of dust over a long period of time in barns. Perhaps you episodes are caused by a reaction to something other than gluten? Have you had your antibody levels checked to see whether you are still being exposed to gluten?
